GLASS -CLOTH OR FABRIC.

SPECIFICATION forming part of Letters Patent No. 232,122, datedSeptember 14, 1880. Application filed August 5, 1880. (Model) To allwhom it may concern:

Be it known that I, HERMANN HAMMES- FAHR, a citizen of the UnitedStates, residing at Pittsbnrg, in the county of Allegheny and State ofPennsylvania, have invented certain Improvements in Glass Cloth orFabric, of which the following is a full, clear, and exact description,reference being had to the accompanying drawings,in which- Figure lis aview, in perspective, of a spunglass fabric or cloth in which silk,woolen, or other fibrous material or silver or other line wire is usedto strengthen the fabric. Fig. 2 is a view in which the entire fabric ismade of the spun glass.

The object of my invention is to furnish an article of manufacture to beused in the various arts for which it may be applicable and useful; andthe invention consists in making a fabric or cloth, either in whole orin part, of

fine-spun glass.

In the manufacture of so-called glass cloth as heretofore practiced theglass has been in-, 'troduee'd only in comparatively small quantities-i.a, in the shape of an ornamental pattern having silk, wool, cotton, orother fibrous material as the basis or. ground-work, and in such casesthe glass forming such part has of necessity been protected from theaction of the reed in weaving by strands of silk or other fibrousmaterial.

Referring to the drawings, A in Fig. l designates the filling of glassfibers, and B the weft of silk or other fibrous material, and for somepurposes silver galvanized or other suitable fine wire may be used asthe weft in lieu of the silk.

As heretofore indicated, Fig. 2 represents a fabric made entirely ofglass, spun very line and woven in any suitable manner.

The glass I use is made of soft and rich materials in order that it maybe spun very line and at the same time possess the requisite degree oftoughness to be woven in the loom and to withstand the beating up of thereeds of said loom without breaking into fine particles. it is spun fromsolid rods of glass about one-half (g an inch thick.

The spinning of the glass into threads is accomplished in any well-knownmanner; but a Wheel of large so that when dra-wuinto composed of silk,satin,

diameter is preferred, The i rod of glass having the end nearest thewheel exposed to a blow-pipe flame, the soft metal is attached to theperiphery of the wheel and said wheel setin motion, the quality of theglass threads being regulated by the velocity of the number ofrevolutions made by the wheel per minute.

Various colors may be spun on the wheel at the same time, or thedifferent colors may be spun' separately.

' The glass having been spun, it is cut and arranged in a loom ofordinary or suitable construction and woven into cloth either with orwithout silk, woolen, or cotton strands, or fine wire of any suitable orornamental character. 7

he glass I use is made of much finer materials than the glass commonlyused, and the color of said glass must be very dark or dense,

fine threads the 001- ors will'show. Light colors, whenldrawn into finethreads, do not show except in reflecting the light.

This fabric is capable of being used for shawls, table-covers, neckties,bonnets, and in fact all articles of fancy clothing. It can also be usedto good advantage for filtering purposes, also woven or wrapped aroundtelegraph-wires for insulating purposes.

I am aware that it is not new to spin glass into fibers. 3

I am also aware that fabrics have been made in which glass fibers havebeen used to form ornamental portions; but in all such previously-madecloth the main parts have been woolen, cotton, or other similar fibrousmaterial.

Having thus described my invention, what I claim, and desire to secureby Letters Patout, is-- v 1. A woven fabric or cloth composed wholly ofor the principal parts of which are composed of spun glass, as setforth.

2. As a new article of manufacture, a fabric or cloth composed wholly ofor the principal 5 parts of. which are composed of spun glass woven.
